You're waiting for labor to begin, and everyone tells you to "time your contractions." Sounds simple enough. But when that first real pang hits, a wave of uncertainty follows. Was that the start? Is it over now? That moment of doubt is where most guides fail you. They talk about clocks and apps but skip the crucial, physical awareness you actually need.
Knowing the precise start and end of a contraction isn't just a technical exercise. It's the primary data point your healthcare team uses to assess your labor's progress. Get it wrong, and you might head to the hospital too early (hello, sent-back-home disappointment) or too late (a much more stressful scenario). After years in birth spaces, I've seen this confusion firsthand. Let's cut through the noise.

What a Contraction Actually Feels Like (It's Not Just Pain)
First, let's reframe the word "contraction." It's not just a cramp or a backache. It's your powerful uterine muscle working. Imagine your uterus as a fist. During a contraction, that fist slowly clenches tightly, holds the squeeze at its peak, and then slowly, deliberately releases.
The sensation builds. It peaks. It recedes.
Early on, it might feel like a strong menstrual cramp that wraps around from your back to your front. Or intense lower back pressure. For some, it's a tightening with minimal pain—like your belly is turning into a hard basketball. The key is the wave-like pattern: a clear beginning, buildup, climax, and fading.
How to Pinpoint the Start and End: A Step-by-Step Sensation Guide
Forget the clock for a minute. Close your eyes and tune into your body. Here’s what to physically feel for:
Identifying the START of a Contraction
The start is subtle. It's not the moment you go "Ouch!" That's usually the peak approaching.
The true start is when you first notice a change in your uterine muscle tone. It goes from soft and relaxed to beginning to tighten or firm up. You might feel:
- A low, deep cramp beginning in your lower back or pelvis.
- A sensation of squeezing that starts at the top (fundus) of your uterus and moves downward.
- A gradual hardening of your belly when you touch it.
Pro Tip: Place your hand lightly on your lower abdomen. The start is the moment you feel the muscle begin to tighten under your palm. Don't wait for it to become rock hard.
Identifying the PEAK of a Contraction
This is the most intense part. The muscle is fully clenched. The sensation—whether it's pain, pressure, or both—is at its maximum. Your focus will naturally narrow here. It's okay. Just note it.
Identifying the END of a Contraction
This is where almost everyone gets it wrong.
The end is not when the sharp pain starts to fade. That's the contraction beginning to release from its peak, but the muscle is still actively working.
The true end is when your uterus feels completely soft and relaxed again. The tension is fully gone. Your belly feels soft to the touch, like it did between contractions. The sensation has completely melted away.
There's often a distinct feeling of relief or a quiet pause before the next wave begins.
Practical Timing Methods: From Paper to Apps
Now, bring in the clock. You're tracking two things: Frequency (time from the start of one contraction to the start of the next) and Duration (how long each contraction lasts, from true start to true end).
The Low-Tech, Foolproof Method: Paper and pen. Draw two columns: "Start Time" and "Duration." When you feel a contraction begin, note the clock time. Don't start a stopwatch. When it fully ends, count or estimate how many seconds it lasted ("45 sec," "1 min"). This method forces you to identify the endpoints clearly. It's what many seasoned doulas use because it's less distracting.
Contraction Timer Apps: FullSpectrum Birth or Contraction Timer are popular. They're convenient—tap at the start, tap at the end. But the app's algorithm often assumes your tap marks the true end. Be disciplined. Don't tap until you feel total relaxation.
My personal take? Use an app for convenience once you're confident, but start with paper to train your awareness. I've seen moms glued to a phone screen, anxious about the numbers, instead of breathing through the sensation. The tool should serve you, not add stress.
Real vs. False Labor: The Tell-Tale Differences
Braxton Hicks contractions ("practice contractions") love to mimic the real deal, especially in the final weeks. Here’s how to tell what you're feeling.
| Feature | Real Labor Contractions | Braxton Hicks / False Labor |
|---|---|---|
| Pattern | Get progressively longer, stronger, and closer together over time. They establish a rhythm. | Irregular. Spacing and intensity don't change consistently. |
| Location | Often start in the back and wrap to the front. The whole uterus hardens. | Often felt only in the front or one area of the belly. |
| Effect of Movement | Continue or intensify with walking, position changes, or activity. | Often ease up or stop if you change position, walk, rest, or hydrate. |
| Discomfort Level | Intensity steadily increases. You cannot talk through the peak. | Usually mild to moderate, and intensity is static. |
| Cervical Change | Work to dilate and efface the cervix. (Only a provider can confirm this.) | Do not cause cervical change. |
The "change with activity" test is one of the most reliable at home. If a warm shower, a glass of water, or lying down makes the contractions fizzle out, it's likely false labor. Real labor contractions have a job to do and they persist.
When to Actually Call Your Provider or Go to the Hospital
General guidelines are helpful, but they're not one-size-fits-all. Here’s a breakdown:
The 5-1-1 Rule (for first-time moms): This is standard advice. Call when contractions are about 5 minutes apart, each lasting 1 minute, for 1 hour straight. This usually indicates active labor.
But listen to your body's signals, which are often more urgent than any rule:
- Your water breaks (a gush or a steady trickle). Note the color and time, and call regardless of contractions.
- You have vaginal bleeding heavier than a period-like show.
- Contractions are immediately very intense and close together (e.g., 2-3 minutes apart) from the get-go.
- You feel intense, constant pain unlike the wave-like pattern of contractions.
- You feel significantly less fetal movement.
For second-time (or more) parents, labor often progresses faster. Your "go-time" might be at 7-1-1 or even 10-1-1. Discuss a personalized plan with your provider beforehand.
Common Mistakes and Pro-Tips from the Delivery Room
Let's wrap up with the unspoken stuff—the tips you learn after seeing hundreds of labors.
Mistake #1: Timing from the first twinge. Early labor can have odd, sporadic sensations. Wait until you have a clear pattern of 3-4 distinct contractions before you officially start tracking. Otherwise, you'll drive yourself crazy with false starts.
Mistake #2: Partner panic. Often, the support person is the one frantically watching the clock. Hand them this guide. Their job is to help you focus on sensation, not become a stressed-out timekeeper.
Mistraction #3: Obsessing over the app. If timing is increasing your anxiety, put the phone down. Labor is a physical process, not a digital one. The trend over an hour is more important than any single contraction's length.
One final, crucial tip: The definition of a contraction's "start" can subtly change as labor advances. In early labor, the start is that gradual tightening. In active, pushing labor, the start might feel more abrupt and intense. Don't get rigid with your definition. Your body's doing the work; you're just observing it.
